This is a great story. Anyone who starts a business of their own is to be commended! "Any level" of success is of value as much can be learned from the process which can lead to further success. I am sure that Ms. Cain's business will continue to grow & she will reap the rewards of her hard work.
Regarding "Ms.sideviews" childish & needless comment, it looks like an 11 year old wrote your pointless reply.
FYI- There is no problem with going into a business where there are plenty of people doing the same thing. If others are successful in that field, then it's a big pie & therefore you only need a small slice (ie. its far easier to get a slice of an existing pie, than to bake your own from scratch).
